This was the best image I came up with. It's amazing how far the shadow is offset from the moon compared to two night previous.
I seem to have lost collimation between the previous Jupiter and this one. Scope hasn't been touched so I'll just have to check more frequently regardless. This has not been de-rotated as that seemed to make it worse! Must be a data quality thing. I also changed Autostakkerts Quality Estimator/Noise Robust value to 2 (usually I use 4) and that made a big difference, finding finer detail in the video stream.

You are blazing along Duncan!!
That is very similar to the position of my image - though mine is accidentally rotated 180 degrees.
For one reason or another that isn't up to the standard we're used to from you. Maybe the collimation, maybe the seeing, maybe the transparency. However, Callisto has come out much brighter than mine.
I find it interesting that you manage to get 31 frames/sec at a shutter speed of 49.5ms - is this some time dilation effect? :D
